WET-ORE CONCENTRATOR.

SPECIFICATION forming part of Lettera Patent No. 343,241, dated June 8, 1886,

Application filed October 19, 1885. Serial No. 1:05255. (No model.)

To all whom, it may concern:

Be it known that I, JOSEPH HUBERT, a citizen of the United States,v residing in the city and county of San Francisco, in the State of California, have invented certain new and useful Improvements in Vet-Ore Concentrators; and I do hereby' declare that the following is a full, clear, and exact description of the same, reference being had to the drawings accompanying and forming part of this specication.

My invention relates to improvements in ore separators and concentrators of the kind in which the material is subjected to the joint action of a stream 0r flow of water and a vibratory motion upon a hat concentrating table or surface.

The arrangements and combinations of the parts or mechanism are such as toproduce an improved machine having great capacity and efficiency, and particularly adapted for working over the tailings from mills and other apparatus. l

Referring to theaccompanying drawings, in

three sheets, Figure lis a plan or top view ofv my device. Fig. 2 is an elevation in section of same. Fig. 3 is a cross-section on v Fig. 2, through the barrel. Fig. 4 is a detail view ofthe pitman. Fig. 5 is an end view taken from the right-hand endvof Fig. 2, and Figs. 6 and 7 show the construction of the tablecarrying track and wheels.

A A* represent timbers forming a stout solid frame to bear the vibrating table B, and A2 A3 are other timbers that support the barrel C and its driving mechanism. On the cross-sills A* are set iianged wheels D D, having concave grooved rims and mounted in axle-boxes dd. Two sets of these wheels are used-one under the front end and the other set under the rear end of the table-and rails EE, corresponding in shape in cross-section to the form of the wheel-grooves, are secured on the bottom of the table. These rails are made of half-round bars with flanges e e, to bolt them in place. They, are set back from the ends of the table to keep out the sand and matter from the wheels and bearings. Over the front end of the table or that end where the material is introduced a winding-shaft, G, is set in upright posts F F in sockets ff, so as to turn readily, and a hand-wheel, HX, and the pawland-ratchet wheel I I are provided as a means for rotating the shaft to wind and unwind the chains H H and hold them at any point. The ends of the chains are attached by hooks h h to eyes on the top of the table. The purpose of this winding mechanism is to raise and supe port the front end of the table at diit'erent inclinations greater than the angle orv position it takes when it is supported by and is traveling onthe track at that end, as in operating upon material of different or varying grades or characters of composition and richness it will sometimes be required to accelerate the dischargesof the upper portion of the current of water and the suspended matter. This is accomplished by turning the shaft G until the desired pitch of the table is obtained, or for reducing the pitch by raising the pawl and unwinding the chains. In lifting the front vend of the table from the wheels D the weight is sustained by the chains, but the rear end remains upon the rear set of wheels and rides back and forth under the movement applied to the table by the shaft J. The construction of the rails and carrying-wheels permits this adjustment of pitch in the table without disturbing its position with relation to the rear set of wheels, and without throwing any irregular strain or pressure on the wheelaxles. This will be understood by referring to Figs. 2 and 7.

On the sides of the table at the rear end are projecting guide-rods wx, set in line with the rail D and working through guides WV on the frametimbers, as seen in Figs. 1 and 2. The table, having free lateral movement upon the wheels between these guides, also swings on the centers w as thehigher en d is raised and lowered. t

The table has a flat surface and a rim, r b, around the sides, the height of which increases from the front to the rear end, so that at the rear the depth of the concentrating-surface is greatest. At this end are discharge slots or apertures?)X bx. The surface is divided into compartments by partitions B2 B3, running both longitudinally and transversely, and of regularly-increasing height from the front toward the rear end, as shown in Fig. 2 of the drawings.

At the higher or receiving end the table has a number of partitions, B* Bi, set in a divergent manner from that portion of the table IOC surface directly under the end of the barrel, and running outwardly to the first transverse partition. These partitions serve to distribute the matter over the table-surface, and also to form pockets or obstructions, in the usual manner, to catch the metallic particles as they are separated under the influence of gravity and the action of the current and the movement of the table.

The shaft J carries a short crank, k, and a pitman, K, is attached to the bottom ofthe table at k2 by a suitable connection. The outer end of the pitman is connected with its crank by a swivel-joint, L, (shown in Figs. 1 and 4,) for the purpose of permitting the table to be raised or lowered from the front or upper end without affecting the movements of the pitman or straining the crank and shaft. The shaft J is set in boxes m m on the bed-timbers, and is furnished with a pulley, JX, for an engine-belt. The main driving-shaft J is also provided with a fast and a loose pulley, as shown at J XX, from which a belt, J, extends to the fast and theloose pulleyj on the conn- The barrel C is a cylinder with one end open and the other end closed by a head, in which is a circular opening at the axis, for the end ofa supply-hopper, Y, and in this opening provision 'is made for delivering a stream of water with the ore matter into the barrel by having an inlet, X, with a coupling, wx, for a water-pipe. The barrel is mounted in substantially a horizontal position in the frame A2 A3, and is driven by suitable gearing from aconntershaft, U, to which motion is given by a belt, J from the principal shaft J. Rotation is given to the barrel by the gears S T i, the first one being a toothed ring on the barrel, engaging with the gear T, and the last one a pinion on the counter-shaft U. These gears bring down the motion of the barrel to a considerably less rate of speed than that of the table. In the present construction the proportions ofthe gearsTt are as six to one, and the table moves about eight times as fast as the cylinder. One part or section ofthe inner surface of the barrel is furnished with flanges 0*, for lifting and dropping the material. They are set longitudinally at regular distance apart, and areconined to the front end,or that portion of the barrel where the material is received. In the space in rear of these iianges are two circular guide-ribs, C, (seen in Figs. 2 and 3,) which form a track for a grinding and scouring roller, P. This roller is set loosely in the barrel, but is kept in position by grooves p, near either end, into which the tracks C3 fit. The material under treatment thus receives, first, the action of the flanges, and becomes thoroughly broken up and mixed with the stream of Water, and afterward is acted on by the revolving roller in passing outward to the concentrating-table. The barrel is carried in the usual manner by iianged rollers B B and tracks C.

In the operation of this machine, the material, being introduced into the barrel with the stream of water, is brought into such condition before reaching the table that the separation and concentration will be effective and complete. In the case of some qualities or conditions of tailings it insures the recovery of many particles that are liable to be floated and carried off by the constantly flowing stream of water.

Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is-

l. The herein-described wet-ore concentrator, comprising the following mechanism: the revolving barrel C, having the feed-hopper and an inlet for water, the internal flanges, C*c C*,and roller P, the inclined vibrating table B, having'riiles and distributing partitions B2 Bx B4 and discharge-apertures bx, the principal shaft J, for operating both the barrel and the table, the crank k on shaft J, and the pitman connecting it with the table at one end, a counter-shaft, U, near the other end of shaft J, and gears by which rotation of the barrel is produced, as set forth.

2. The herein-described wet-ore concentrator, comprising the barrel C, having a supplyhopper and an inlet for water, iianges C* 0*, and roller P, and the inclined concentratingtable B, wheels D D, shaft G, chains H, and a hand-wheel and locking device for suspending and adjusting one end of the table, a rotating driving-shaft, J, and suitable gearing for connecting and operating said barrel and table.

3. A wet-ore concentrator comprising the inclined concentrating-table B, the grooved wheels D D, on which said table is mounted, the shaft G, and chains H, for suspending the table at the front end, means for adjusting its inclination, the Shaft J, having crank k, the pitman K, and the swivel-joint L, substantially as and for the purpose set forth.
